gator + upper blade on hrc216

i have not mulched with these mowers yet but would like to try,
i have read that the 2 blade setup from honda doesnt work as well as the gator blade.
Has any one tried a gator blade with the upper blade from the honda kit?
was just wondering how this works

I use the double stacked blade set up on my 21" Honda commercial, with excellent results, wet, dry, tall, short, just slow down a little in adverse conditions.
As for stacking a gator and Honda's top blade, don't know if you'll have clearance. Probably leave top blade off if using a gator.
Like to know if you do try, and the results.
